[COMSOL_Users] Overlap integral caculation in Comsol

[xinyangyang_2006]

Dear all,

I am trying to do some simulations in integrated optics with
comsol.I come across a problem recently. As you know, it is easy to
calculate the subdomain integration of electric fields
(Ex,Ey,Ez,Hx,Hy,Hz) of the same eigen mode with comsol in GUI
interface. However, how to obtain the subdomian integral of two
electric fields of two different eigen modes? (for example, Ex1(eigen
mode 1)*Hy2(eigen mode 2)
It may be hard to realize in comsol GUI interface. How about comsol
script? And how to extract each elctric (or magnetic) field element in
every diretion from the fem.sol.u?

Thank you very much in advance!

You can do it in the GUI. Use the "with" operator.

Thank you for your reply! However, would you please give me more
details? The expression in the integral is the multiplication of the
electric fields of two different eigen modes(i.e., with different
eigen values).

Thank you very much!
